What is the Guardian Engine MCP server?

Connect Guardian Engine to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Deterministic recipe verification engine — validates AI-generated recipes against master SOPs. The guardian engine mcp server is what makes that connection.

What the server does

Guardian is a hosted MCP server. No install, no API key, no Docker. Pick your client and paste the config.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Machine — actionable repair** — findings come with structured patches (and fix_recipe can apply them deterministically); your agent authors the rest and
  • Cursor — Open Settings → MCP Servers → Add new MCP server, then paste:
  • Windsurf — The Windsurf tool exposed by this server
  • verify_recipe — Verify a candidate recipe against a Guardian master spec. Returns a structured report with a strict PASSED/FAILED verdict (no scores) and detailed
  • fix_recipe — Deterministically repair a candidate recipe against a master spec. Verifies, applies every machine-actionable patch the symbolic engine produced
  • list_dishes — List all master recipes Guardian can verify against, with rich metadata (slug, title, cuisine, region, aliases, complexity)
  • get_master — Return the canonical master recipe for a dish — a pure knowledge-base lookup, no LLM. Enables compare-then-verify loops: fetch the master, diff
  • check_safety — Master-independent safety checks for any recipe — no dish resolution or master spec required. Checks poultry internal-temperature safety (≥ 74
  • check_allergens — Check an ingredient list for EU FIC 1169/2011 allergen presence, with a detailed audit trace mapping each ingredient to its Annex II allergen group
  • verify_dietary_claim — Verify that a recipe satisfies a dietary claim, returning a structured verdict with the specific offending ingredients — never a vague paraphrase

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Where it fits

This sits in the AI and media services group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Guardian Engine's toolset — Machine, Cursor, Windsurf and 7 more — is a fair guide to whether it matches your workflow. It is maintained by dev.kaimeilabs; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Guardian Engine's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 10 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Guardian Engine.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Guardian Engine to MCP-compatible AI assistants such as Claude and Cursor, exposing 10 tools (Machine, Cursor, Windsurf, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Guardian Engine directly.
